Walker Products 250-241052 oxygen sensor for the 2012-2014 Ford Expedition V8 5.4L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. This Walker Products oxygen sensor is a 4-wire, direct-fit narrow-band unit made for its specific fitment position.
- Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
- Measures oxygen levels so the air-fuel mixture can be fine-tuned for fuel economy
- Monitors exhaust gases to help reduce pollutants
- Electrodes coated with a gas-permeable platinum layer
- Coating protects the electrode surfaces from combustion residue and particulates in the exhaust gases
Quick facts
- Part: Walker Products 250-241052 oxygen sensor
- Fits: 2012-2014 Ford Expedition V8 5.4L and other vehicles
- Position: Downstream, downstream left, downstream right
- Condition: New
Rough running, higher fuel use or a lit malfunction indicator light can mean the oxygen sensor is failing. Before you replace it, look over the sensor, its wiring harness and the connector for physical damage with the engine off and cool, since other faults can look alike.
Fits
Among the vehicles it fits are the 2012-2014 Ford Expedition V8 5.4L, the 2011-2016 Ford F-350 V8 6.2L and the 2012-2016 Ford F-250 Super Duty V8 6.2L. This listing is one sensor, and the 2012-2014 Ford Expedition V8 5.4L takes one. If your vehicle is not named here, open the "Vehicles it fits" section to check your exact model and engine.

Frequently Asked Questions
Is this Expedition oxygen sensor right for the 2012-2014 Ford Expedition V8 5.4L?
Yes. Walker Products 250-241052 is a direct-fit oxygen sensor for the 2012-2014 Ford Expedition V8 5.4L, and the fitment calls for one sensor.
Is this the Ford F-250 Super Duty oxygen sensor for a 2012-2016 truck with the V8 6.2L?
Yes. The 2012-2016 Ford F-250 Super Duty V8 6.2L is on the fit data for this oxygen sensor, which is sold as a single sensor.
What type of oxygen sensor is the Walker Products 250-241052?
It is a narrow-band, direct-fit sensor with four wires and an M18 - 1.5 thread. Its electrodes are coated with a gas-permeable platinum layer.
Will a bad oxygen sensor set a warning light on my vehicle?
It can. Newer vehicles store fault codes in the ECU, some tied to the affected sensor and its related systems, and a failed sensor may also light the malfunction indicator light.
What does the Walker Products 250-241052 report to the ECU?
Walker Products 250-241052 measures the oxygen in the exhaust gas. It is made for its specific application and fitment position and gives the ECU the relevant diagnostic system feedback it requires.
